.OlL-WELL RIG.

SPECIFICATION forming part: of Letters Patent; No. 371,573,61ated October 18, 1887.

Application filed Dtcember 16, 1 86. Serial No. 221,807. (Noinodehl To all whom it may concern.-

Be it known that 1, WILLIAM Fons IE, 21 citizen of Canada, residing at \Vashington, in the county of \Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Oil-XVell Rigs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in oil-well rigs, the object being to provide a means for operating the sand-reel, and also to provide a simple and durable means of connecting the crank to the walking-beam; and with these ends in view my invention consists in certain details of construction and combination of parts, as will be fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of an oil-well rig constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged sectional plan view of a portion of the gearing, showing a new and improved method of operating the sand-reel. Fig. 4 is an enlarged view ofa device for attaching the connecting rod to the walking-beam. Fig. 5 is a sectional view showing the manner of connecting the walking-beam to the vertical standards.

To put my invention into practice with an oil-well rig, such as I have shown at Figs. 1 and 2 of the drawings, I provide a frictionclutch consisting of two conical sections, a and b. The one 12, I attach to the fly-wheel J, keyed on the main shaft 0, and the other to a belt-wheel, e. This belt wheel e, I connect by means of a belt, to, to another, (I, secured to a shaft, m, in suitable bearings, 12, carrying a reel, f. Attached to the belt-wheel e areasystem of levers, 9, connected to a rod, h, which leads to a lever placed within easy reach of the operator while drilling. By moving this red It back or forward the clutch is engaged or released at will, as will be fully described hereinafter.

To the lower end of the connecting-rod i, I arrange a sliding block, j, operated by a bolt, p, and crank-nut k, whereby the journal L may be attached or disengaged easily from the crank Z.

\Vhen it is desired to operate the sand-reel f, the red It, by means of a lever, is drawn toward the well, which action, by means of the leversgg, moves the belt-wheel eend wise on its shaft 0, and by means of the impingement of the clutching portions to b engages the beltwheel with said shaft 0, thereby giving rotation to this wheel.

One of the levers g has its fulcrum at t (see Fig. 2) on the horizontal frame, and one end of this lever receives freely through it the shaft 0, and is connected by loose bands 12 to the hub of the wheel 6. The other end of said lever g is jointed to toggle-levers g g, to the joint 8 of which the rod h is suitably pivoted.

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent,

In an oil-well r g, the combination, with a suitable frame, of the shaft 0, provided with a crankarm on one end for vibrating a walking-beam, the flywheel J, keyed on shaft 0, conical clutches a b, the belt-wheel e, loose on shaft 0, its belt and sand-reelf, the levergand its loose connections with the beltwvheel, the toggle levers g, and the rod h, all constructed and adapted to operate substantially as and for the purpose described.

WILLIAM FORGIE.
